Description
These Costco Marshmallow Crispy Cookies are a nostalgic mashup of rice crispy treats and chewy cookies, loaded with gooey marshmallows and crispy cereal in every bite. Soft, buttery, and delightfully sweet, they’re the ultimate comfort treat.
Ingredients
1 cup unsalted butter, softened
1 cup brown sugar, packed
0.5 cup granulated sugar
2 large eggs
2 teaspoons vanilla extract
2.5 cups all-purpose flour
1 teaspoon baking soda
0.5 teaspoon salt
2 cups crispy rice cereal
1.5 cups mini marshmallows
1 cup white chocolate chips (optional)
Instructions
1. Cream together the softened butter, brown sugar, and granulated sugar until light and fluffy.
2. Add in the eggs one at a time, then mix in the vanilla extract.
3. In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add this to the wet mixture.
4. Fold in the crispy rice cereal, mini marshmallows, and white chocolate chips.
5. Scoop dough into heaping tablespoons and place on a parchment-lined baking sheet. Chill for 20–30 minutes.
6. Bake at 350°F (175°C) for 10–12 minutes, until edges are golden and centers slightly soft.
7. Let cool on the baking sheet for 5 minutes before transferring to a wire rack.
Notes
Chill the dough to keep marshmallows from overmelting.
Add a few extra mini marshmallows on top before baking for a gooier finish.
Store in an airtight container or freeze for later.
